As the Avengers and their allies have continued to protect the world from threats too large for any one hero to handle, a new danger has emerged from the cosmic shadows: Thanos. A despot of intergalactic infamy, his goal is to collect all six Infinity Stones, artifacts of unimaginable power, and use them to inflict his twisted will on all of reality. Everything the Avengers have fought for has led up to this moment - the fate of Earth and existence itself has never been more uncertain.

Trivia, insights & behind the scenes
Josh Brolin performed Thanos through motion capture wearing a camera rig on his bald cap — the 'Thanos chin' is all him.
The snap sequence was filmed completely secret from most cast; actors learned their fates only at the premiere.
